Chemical Composition, Antioxidant, Antimicrobial and Antidiabetic Potential of Philodendron Bipinnatifidum Schott ex Endl

Many of the species used in popular medicine do not have their biological activities already proven by scientific studies. Among these species, the endemic South American Philodendron bipinnatifidum Schott ex Endl deserves special attention since it is already in use in popular medicine for inflammation cases, such as erysipelas, orchitis and ulcers. This study evaluated the antioxidant, antimicrobial and antidiabetic activities of extracts of the hastes de P. bipinnatifidum. The ethanolic extract showed a significant antioxidant potential. The ethyl acetate extract resulted in high antimicrobial activity against Streptococcus pyogenes. The most significant biological activity of ethyl acetate extract relates to its chemical composition when compared with ethanolic extract, which showed the highest concentration of bioactive compounds. In vitro antidiabetic activity was only evaluated for ethyl acetate extract, resulting in inhibition of intestinal disaccharidases (maltase and sucrase) at concentration of 500 μg/mL.
